How does the calculation work?

The calculator uses the scientifically proven Mifflin-St Jeor equation to estimate your basal metabolic rate.

Vitals
Age, weight, and height dictate how many calories you burn at absolute rest (BMR).
Activity Level
Multiplies your resting rate based on how much you move (TDEE).
Hydration
Calculated from your weight (~35 ml per kg) plus extra ounces if you exercise heavily.

Frequently asked questions

What is TDEE and a Caloric Deficit?

TDEE is the total calories you burn in a day. A caloric deficit (typically -500 kcal from TDEE) is required for weight loss.

The recommended calories are too low (under 1200 kcal). What should I do?

Consuming less than 1200 kcal daily without medical supervision is generally unsafe for adults. Increase your activity level to increase your TDEE instead.

Why track calories and hydration?

Monitoring your caloric intake isn't just a diet trend, it's about understanding how to fuel your body correctly according to your goals. Giving your body fewer calories than it burns leads to fat loss, while surplus calories build muscle if training right. Equally important is hydration. Water is crucial for cellular function, skin health, and weight loss. When dehydrated, your heart works harder, and you feel lethargic. Combining correct macronutrient energy with sufficient water guarantees high energy throughout the day.
